DUMPING-WAGON.

Application filed February 4. 1911.

Specification of Letters Patent.

Patented Mar. 19, 1912.

Serial No. 606.562.

10 all whom t may conce/rn.

Be it known that- I, Groenen IV. HonmNn, a citizen of the United Statesof America, residing at ',l`ombstone, in the county of Cochise and Stateof Arizona, have invented new and useful Improvements in DumpinglVagons, of which the following is a speciiication.

This invention relates to dumping \\f'agons, and-has for an object toprovide improved mechanism embodying a plurality of Inovable gates inthe bottom of the wagon box and movable means manually actuated formoving the gates simultaneously to open or closed positions.

In the drawings, forming a portion of this specification and in whichlike numerals of reference indicate similar parts in the severalvie\vs:--I4`igure l is a side view of the dumping wagon showing thegates in closed positions. Fig. 2 is a similar view showing the gates inpartly open positions. Fig. 3 is a similar view showing the gates infull open positions. Fig. 4l is a bottom plan view of the box showingthe gates in closed positions. Fig. 5 is a perspective view of one ofthe links. Fig. G is a section taken on the line 6 6 of Fig. l.

The dumping wagon comprises a body 1 which is provided with the parallelsides 2 and the vertical ends The body 1v has its sides 2 and rear end 3suitably secured to the end bar 4 and the longitudinal side bars 5 of arectangular frame (3. This frame is disposed lowermost in the wagon box,and as shown, it is provided in its bottom with a plurality of normallyhorizontally disposed gates 7. These gates are identically constructed,and as shown, they are provided at their sides at points near their'forward ends with trunnions S which are mounted in the longitudinal sidebars 5, as shown.

0n the underside, near the rear end, each gate has txed thereto a bar t)which is provided at its ends with eyes l0 which extend slightly beyondthe side bars These eyes are pivotally connected with the eyes 'll insubstantially arcuate links 12. The other ends of these links areprovided with inwardly extending trunnions 13 which are mounted incorrespondingly formed passages 14 in the side bars 15 of a movableframe 1G. Suitable guides 17 are secured to the side bars 5 of the fixedframe of the wagon box and they are adapted to guide the links 12 intheir movements.

The movable iframe 16 has its side bars 15 connected at their rear endsby a cross bar 18 and at the front ends the said side bars are connectedby a cross bar 19. A substantially U-shaped member Q() is pivoted to theunder-sides of the side bars 5 near their front ends, as at 21, and asillustrated, the side member 22 of this member extends upwardly againstone of the side bars and its terminal is formed to provide a trunnion 23which is suitably mounted in one of the side bars V15. ',lhe oppositeside bar 15 is formed to provide a controlling lever 24 which extendsthrough the eye 25 which is pivotally mounted on the opposite side bar15. The lever is provided with a suitable well known forni of pawl orlocking dog 2G which is designed to engage the rack segment 2T at. oneside of the frame The front bar et of the fixed frame (3 has securedthereto a downwardly inclined footboard QS which extends in thedirection of the bottom of the wagon box.

From the construction described it will be seen that the side bars 15 ofthe movable frame are accurately guided in their movements by thevertical sides of the wagon box, and in view thereof, the links l2 willbe held against lateral strain. Normally the side bars 15 of the movableframe lie directly upon the upper surfaces of the side bars 5 of thelixed frame substantially throughout the length of the bars 5, as shownin Fig. l of the drawings.

`In operation, when it is desired to dump the load the controlling lever24 is moved rearwardly so as to move the movable frame lb upwardly andrearwardly and downwardly so that the forward pivoted ends of the linkswill be disposed substantially immediately above the guides 1T. In thisposition of the links the gates will be in their full open positions,and as shown in Fig. 2:3 of the drawings. the side bars l5 of themovable frame rest directly upon the upper surfaces ot' the side barsl 5of the .fixed frame so that the weight of the load to be dumped will beequally distributed to the gates and to the movable frame.

In practice it has been found that the trunnion 23 of the U-shapedmember Q0 is sullicient. to lift the frame 1.(3 in the operation of thelever 24, and the lever 24 by its engagement with the eye 25 which ispivotally secured to one of the side bars 15 of the frame 1G has atendency to cooperate with the trunnion in this lifting action by meansof the :trictional-oontact between the said lever 24 and eye 25. Thislifting of the frame reduces the friction between the of movable gatescarried by the fixed frame and normally closing the bottom of the box, amovable gate-controlling iframe wholly Contacting with the fixed frameon open or closed positions of the gates, operative connections betweenthe movable frame and the gates for moving the gates on movement of themovable -frame, and a controlling lever Connecting the fixed frame withthe movable frame.

2. A dumping wagon comprising a box, a fixed frame mounted thereon, aplurality of movable gates carried by the fixed frame and normallyclosing the bottom of the box, a movable gate-controlling framecontacting with the fixed frame in open or closed position of the gates,operative connections between the movable frame and the gates for movingthe gates on movement of the mov able frame, a substantially U-shapedmember pivoted to the fixed frame, connections between said member andmovable frame and a controlling lever for operating said member to movethe movable frame to open or close the gates.

3. A dumping wagon Comprising a box, a fixed frame mounted thereon, aplurality of movable gates carried by the iixed frame and normallyclosing the bottom of the box,

a movable gate-controlling frame contacting 40 with the fixed frame inopen or closed position of the gates, a substantially U-shaped memberpivotally Connected to the under side of the fixed frame, one end ofsaid member forming a trunnion tor supporting the movable frame, acontrolling lever formed upon the opposite end of' said member, andmeans carried by the movable frame and engaging said controlling lever,said lastnamed means and said trunnion serving to move the movable framein the operation of the lever.

In testimony whereof I affix my signature in presence of two witnesses.
